The ending is played with an "Am" chord while walking the bass down on the 6th string from "G", to "F#", to "F", and then playing an "E". After that, you will play a decending scale. When you practice this scale, be sure and watch how my thumb and index finger will alternate playing the notes. That is where you will get the speed for this little riff. When you add all of this together. You end up with a cool instrumental called, "Wayfaring Stranger"
